Our Mission, Old Westbury Gardens seeks to inspire appreciation of the early 20th century American country estate through faithful preservation and interpretation of its landscape, gardens, architecture, and collections.

We hope you enjoy our home!

But, always, there is a larger goal here and that is to make each visitor to our gardens feel as if they are guests of Margarita and Jay Phipps.”
